Aortic Artery Pulsatility Index (API) Estimated by Echocardiography and Prognosis in Patients with Decompensated Heart Failure.
Article in Journal of cardiovascular echography. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Aim of Study: Role of noninvasive aortic artery pulsatility index (API) estimated by echocardiography to predict the prognosis in patients who hospitalized with decompensated heart failure (HF) during hospital course and for 3 months after discharge with comparing this prognosis with KCCQ score. Patients and Methods: The study was occurred on 115 patients who hospitalized at Helwan University Badr Hospital with manifestations of decompensated heart failure (DHF) which is defined in patients whose left ventricular systolic function <40% and were stable on their medications then suddenly developed rapid deterioration in symptoms and signs of HF that need hospitalization. API is the ratio of (difference between systemic systolic pressure and systemic diastolic pressure) to pulmonary capillary wedge pressure which detected by echocardiographic equation as 1.9+ (E/é X1.24). Results: Patients with API values below cutoff value (1.45) had sensitivity 73% and specificity 98% (area under the curve = 0.908, Conclusion: Noninvasive API can predict the mortality and various clinical complications as cardiogenic shock, myocardial infarction, fatal arrhythmias, and stroke in patients with DHF during hospital course and HF rehospitalization, mortality after hospital discharge for 3 months.
